The present invention relates to novel phosphonates.

It is an object of the present invention to prepare phosphonates of polyhydric alcohols having at least three hydroxyl groups.

Another object is to prepare novel heterocyclic acetal and ketal phosphonates.

A further object is to prepare novel phosphonates by the hydrolysis of acet-al and ketal phosphonates.

A still further object is to prepare novel open chain acetal and ketal phosphonates.

Still further objects and the entire scope of applicability of the present invention will become apparent from the detailed description given hereinafter; it should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

It has now been found that these objects can be attained by preparing novel acetals and ketals having one of the formulae where R is alkyl, alkenyl, aralkyl or R R is alkyl, alkenyl, aralkyl, aryl, haloaryl or R and R is ethyl, v is O or an integer, e.g., from 1 to 100, n is an integer between 1 and 10, m is 1 or 2;

Where R is alkyl, alkenyl or aralkyl and R and R are as defined above where R is alkyl, alkenyl aryl, haloaryl or aralkyl and R R and R are as defined above Where R R R R R are as defined above and x is an integer of at least 1, e.g., from 1 to 100.

There are also included phosphonates of diacetals and ketals or hexitols such as sorbitoland mannitol. Typical of such materials are compounds having the formula where R R and R are as defined above.

In Formula V no attempt has been made to show the position of the hydrogen atoms on the asymmetric carbon atoms. The position of the acetal and ketal groups also can be varied so long as there are two such groups in the molecule.

The compounds of the present invention are useful as Water dispersible Wetting and suspending agents. They can also be employed as fire retardants for cellulose, cellulose esters, e.g. cellulose acetate, polyolefin resins, e.g. polyethylene and polypropylene.

A particular important use for the acetals and ketals of the present invention is to hydrolyze them to give hydroxyl containing phosphonates. Such hydroxyl contain ing phosphonates have the following formulae ll R7P-O R 3 wherein R7 is as defined above, R is alkyl, alkenyl, aralkyl, aryl, haloaryl or R and R as Ra a R4 R l l l{ (CHrCHO)v(CH2)nC(C in OH OH where R R R R v, n and m are as defined above;

(fi/OGH: /CH2OH R al wherein R is as defined above;

HZCOH HOJJH CHOH Hot) 0 JHO'I|"Riu CHaOH where R is as defined above.

The hydrolyzed phosphonates, i.e. the compounds of Formulae VI, VII, and VIII, have the uses set forth supra and in addition are useful for preparing polyurethanes by reaction with organic isocyanates, e.g. toluene diisocyanate and PAPI (polyphenylene isocyanate averaging about 3 units in the poymer). The polyurethanes can be prepared as foams or as elastomers. The presence of the phosponate group renders the polyurethane flame resistant. The phosphonate need be used only as a portion of the polyols employed. Thus, the use of of a polyhydroxyl containing phosphonate according to the present and 80% of another polyol, e.g. glycerine propylene oxide adduct molecular weight 3000 or polypropylene glycol 2025 will give a polyurethane with improved flame resistance.

The novel compounds of Formulae I through V of the present invention are prepared by Arbuzov rearrangement of the corresponding phosphite prepared according to the parent application. The entire disclosure of the parent application is hereby incorporated by reference.

Thus, there is employed an alkyl halide, alkenyl halide, aralkyl halide, halohydrin or epihalohydrin with a phosphite of the parent application that is isomeric with a phosphonate of Formulae I through V above. The iodides and bromides are preferred although there can also be employed the chlorides. The halides can be employed in catalytic amounts, e.g. 0.5-5 mol precent based on the phosphite to be rearranged. If the hydrocarbon group of the halide is the same as one of the esterifying groups of the phosphite, then no impurities are introduced into the phosphonate product. By employing a large amount of the halide, e.g. 80 mol percent, or perferably 100 mol percent or more, based on the phosphite employed in the Arbuzov reaction, then the product is one in which one of the esterifying groups on the phosphorus atom is removed and the phosphorous atom is directly attached to the hydrocarbon, hydroxyhydrocarbon or epoxyhydrocarbon group of the halide employed. When one of the esterifying groups of the phosphite is aryl or haloaryl, sufficient alkyl halide or the like must be used to replace the aryl or haloaryl group since aryl halides do not normally take part in the Arbuzov reaction. The Arbuzov reaction is usally carried out at elevated temperatures, e.g. 120200 C. at atmospheric, subatmospheric or superatmospheric pressure. The halide remaining after the reaction can normally be removed by distillation.

Among the halides which are employed in the Arbuzov reaction are methyl bromide, methyl iodide, ethyl bromide, ethyl iodide, n-propyl iodide, isopropyl iodide, amyl bromide, amyl chloride, amyl iodide, butyl bromide, hexyl iodide, octyl bromide,

octyl iodide, epichlorhydrin, decyl bromide, epibromohydrin, decyl iodide, epiiodohydrin,

ethylene chlorhydrin, ethylene bromohydrin, ethylene iodohydrin, propylene chlorhydrin, propylene bromohydrin.

dodecyl iodide, octadecyl bromide, octadecyl iodide, allyl bromide, allyl iodide,

allyl chloride,

The compounds of Formulae VI through VIII are prepared by hydrolysis of the compounds of Formulae I, II, and V. The hydrolysis is carried out with the aid of water, preferably with heating, e.g. up to C. The reaction mixture is usually slightly acidic due to the starting phosphonate. After hydrolysis is completed, an alkaline material, eg sodium hydroxide, sodium carbonate, sodium bicarbonate or potassium hydroxide is added to neutralize the product.

Compounds of Formula A and A have many uses. Thus they can be used as water dispersible wetting and suspending agents. They can also be employed as fire retardants for cellulose, cellulose esters, e.g. cellulose acetate and cellulose acetate butyrate, polyolefin resins, e.g. polyethylene, polypropylene, ethylene-propylene copolymers and copolymers of ethylene or propylene with monoolefins having more than 3 carbon atoms.

A particularly important use for the aeetals and ketals of Formula A and A is to hydrolyze them to give hydroxyl containing phosphonates having the following formula R 0 0 Ra Ra R4 R5 \ll I I P(CHzGHO)v(CHz)nC-(C)m R10 OH H or the formula R 0 0 Rs \II I /I(GHzCHO)vCH2C R CHzOH CHaOH B! In Formula B the terms R R R R R R R v, m and n are the same as defined in Formula A and A. The hydroxyl containing phosphonates of Formula B and B have the uses set forth for the compounds of Formula A and in addition are useful for preparing polyurethanes by reaction with organic icocyanates, e.g. toluene diisocyanate and PAPI (polyphenylene isocyanate averaging about 3 units in the polymer). The polyurethanes can be prepared as foams or as elastomers, The presence of the phosphonate group renders the polyurethane flame resistant. The phosphonate of Formula B and B need be used only as a portion of the polyols employed. Thus the use of 20% of a polyhydroxyl containing phosphonate of Formula B and 80% of another polyol, e.g. glycerinepropylene oxide adduct molecular weight 3000 or polypropylene glycol 2025 will give a polyurethane with improved flame resistance.

The novel compounds of Formula A can be prepared by several procedures. Thus they can be prepared in pure form by reacting (l) a trihydrocarbon phosphite, e.g. a trialkyl phosphite, or a trihalophenyl phosphite with (2) at least an equimolar amount of a 4-haloalkyl dioxolane or a 4-haloalkoxyalkyl dioxolane or a 4-haloalkyl dioxane or 4-haloalkoxyalkyl dioxane.

The compounds of Formula A can also be formed by the Arbuzov rearrangements of the corresponding phosphite of parent Patent 3,096,345. If both R and R are aryl, halaryl or tert. alkyl, relatively pure products of Formula A are produced. There is employed an alkyl halide, alkenyl halide, aralkyl halide, halohydrin or epihalohydride with a phosphite of the parent patent that is isomeric with a phosphonate of Formula A. The iodides and bromides are preferred although there can also be employed the chloride. The halides are used in catalytic amounts, e.g., 0.5-5 mol percent based on the phosphite to be arranged in order to reduce the impurities to a minimum. Generally, however, using the Arbuzov rearrangement, however, some impurities are introduced since the R and R group can undergo rearrangement (unless they are aryl, haloaryl or tert. alkyl) as well as the dioxolanyl methyl to form a phosphonate. Additionally a certain amount of the alkyl group or the like of the catalyst can also enter the molecule by direct attachment to the phosphorus atom.

The Arbuzov rearrangement can be carried out at elevated temperature, e.e., 120200 C. at atmospheric, subatmospheric or superatmospheric pressure. The halide remaining after the reaction is removed by distillation.

The halides which can be employed in the Arbuzov reaction include as stated previously methyl iodide, methyl bromide, ethyl bromide, ethyl iodide, n-propyl iodide, isopropyl iodide, amyl bromide, amyl chloride, amyl iodide, butyl bromide, butyl iodide, hexyl iodide, octyl bromide, octyl iodide, decyl bromide, decyl iodide, dodecyl iodide, octadecyl bromide, oetadecyl iodide, allyl bromide, allyl iodide, allyl chloride, methallyl iodide, crotyl bromide, vinyl bromide, oleyl bromide, oleyl iodide, benzyl chloride, benzyl bromide, benzyl iodide, o-dodecylbenzyl chloride, p-dodecylbenzyl bromide, epichlorhydrin, epibromohydrin, epiiodohydrin, ethylene chlorohydrin, ethylene bromohydrin, ethylene iodohydrin, propylene chlorohydrin and propylene bromohydrin.
